Chuang Tzu in dream became a butterfly, <br />And the butterfly became Chuang Tzu at waking. <br />Which was the real—the butterfly or the man ? <br />Who can tell the end of the endless changes of things? <br />The water that flows into the depth of the distant sea <br />Returns anon to the shallows of a transparent stream. <br />The man, raising melons outside the green gate of the city, <br />Was once the Prince of the East Hill. <br />So must rank and riches vanish. <br />You know it, still you toil and toil,—what for?<br /><br />Li Po<br /><br />http://www.poemhunter.com/poem/chuang-tzu-and-the-butterfly/
